SUPERHEATER FOR HOT-WATER HEATING SYSTEMS.

Application filed May 8,

To all whom it may concern:

Be it known that I, LAFAYETTE J. REES, a citizen of the United States, and a residentof Lincoln, in the county of Lincoln and State of Kansas, have invented certain new and useful Improvements in Superheaters for Hotater Heating Systems, of which the following is a specification.

My present invention relates generally to hot water heating systems and more particularly to the ordinary house heating system wherein the gases of combustion normally escape directly through a chimney to the atmosphere and my primary object is the provision of a superheater in such a system so constructed and arranged that the gases of combustion of the furnace which as above stated normally escape directly through the chimney or outlet flue, will be utilized for the additional heating of the water on its way from the boiler to the radiator and also for raising the temperature of the water returning from the radiators to the boiler.

My invention further aims to provide a superheater in the nature of a chamber in communication at one side with the draft pipe of the furnace and in communication at its opposite side with the stack, chimney or other outlet flue, the main supply and return pipes extending through said chambers so that the individual radiator connec tions may lead outwardly through one of the side walls or the top of the chamber and thus leave the main radiator and sup ply pipes within the influence of the heat within the chamber.

In the accompanying drawing which illustrates my present invention and forms a part of this specification, the single figure is a perspective view showing the complete device, the wall of the superheater chamber being partly broken away.

Referring now to this figure I have shown at 10 a conventional boiler furnace such as used in house heating systems utilizing hot water, the boiler 11 of the furnace being supplied with water through return connections 12 and discharging through main supply connections 13. I

I have also shown a portion of a chimney or outlet flue at 14, with which the draft pipe 15, ordinarily provided with a control- 1924. Serial N0. 711,818.

ling damper adjacent to the furnace, usually communicates in a direct manner.

According to my present improvements, however, I propose the interposition of an enlarged superheating chamber between the furnace and the chimney, stack or outlet flue 14, shown at present of rectangular form constructed of bricks as at 16 and mounted upon a suitable base 17 the chamber communicating at one end with the lower portion of the chimney, stack or outlet flue 14 and the latter provided with a damper 18 beyond the superheating chamber so as to make it possible to readily control passage of the products of combustion through the superheating chamber and, indirectly in this manner also control the draft on the furnace 10.

The furnace draft pipe 15 in the present instance opens into the superheating chamber through the end wall thereof farthest from the chimney, stack or outlet flue and nearest to the furnace and the hot water return and supply connections 12 and 13 of the boiler 11 preferably join with single supply and return pipes 19 and 20 respectively, both of which pipes extend within the superheating chamber throughout its full length so as not only to get the full benefit of the heat within the superheating chamber but also provide for the connection of the radiator supply and return leads 21 and 22 at various points along the lengths of these pipes within the superheating chamber, the leads being shown extending outwardly through the top 23 of the superheating chamber, also it is obvious they may be extended through the side walls if so desired.

The result of my improvement is to greatly extend the useful range of hot water heating systems and eflect considerable saving in fuel by virtue of which it obviously constitutes a distinct advance in the house heating art.

I claim:

In a house hot water heating system including a furnace having a boiler provided with main supply and return pipes and also including a draft pipe for the outlet of the products of combustion and a chimney, stack or draft flue, means forming a superheating chamber between the furnace and the stack or chimney, said means being in the nature of a horizontal continuation of the stack and communicating at one end With the latter and into the opposite end I of which chamber the said draft pipe of the furnace opens, said main supply and return pipes of the boiler extending through and terminating Within the said chamber and exposed to the interior thereof and having series of radiator leads projecting through the Wall of the chamber, and a damper in the chimney or stack beyond the said superheating chamber.
